The DNS requirements for Zimbra are the same as any other mail server, you need valid DNS A & MX records. As far as you 'error' is concerned it isn't a Zimbra problem, take a look at this internet search. You also haven't provided the information I asked for, if you don't answer questions you're asked we have to waste time asking the same questions over and over again.
